Pilot Hole Maker – Accessory for All FieldScout TDR Soil Moisture Meters | Spectrum Technologies

The Pilot Hole Maker is an essential accessory for use with all FieldScout® TDR soil moisture meters (TDR 150, 250, 300, and 350). It enables precise insertion of TDR rods into hard or compacted soils without bending or damaging the probes. This tool ensures consistent soil contact and accurate volumetric water content (VWC) readings, particularly in dense, dry, or rocky soils.

Key Benefits:

• Prevents probe damage: safely opens a pilot hole before inserting the TDR rods.
• Improves measurement consistency: ensures complete rod-soil contact for reliable readings.
• Essential for compacted soils: facilitates measurements in dry, clay, or turf surfaces.
• Universal compatibility: designed for use with all TDR models and rod lengths.
• Ergonomic design: easy to handle and durable for field use.

Main Specifications:

• Compatible models: TDR 150, TDR 250, TDR 300, and TDR 350.
• Material: high-strength steel shaft with comfortable grip handle.
• Function: creates a pre-hole in compacted soil for probe insertion.
• Recommended use: before every insertion in hard or dry ground.

Typical Applications:

• Golf courses, sports turf, and sod farms with compacted root zones.
• Agricultural fields and test plots with dry or rocky soils.
• Research stations and soil moisture calibration studies.

Why Choose the Pilot Hole Maker:

• Prolongs TDR probe lifespan by minimizing stress and bending during insertion.
• Ensures accurate and repeatable readings even under challenging soil conditions.
• Durable, field-ready design ideal for repeated professional use.
